What's New in moodunits

2.0.1

October 30, 2026

moodunits now comes with all MUWaverley instruments pre-installed. These were previously available as individual IAP downloads, but unfortunately, as Apple no longer support IAP content hosting, download and purchase restore would fail in earlier versions. You should now see all of the instruments showing as purchased in MU Store, regardless of how many you actually bought. The downside is that the app will now take up significantly more storage, but it's the same as if you'd purchased all the IAPs. And if you didn't, then you've got a few freebies to play with :-) And no more spurious IAP errors - hurrah! Apologies for these issues which entailed having to remove the app from sale for a short period. Minimum iOS version is now 15 due to an enforced requirement for new app updates - sorry about that.

Einige Sounds Moods sind kostenlos, die anderen kosten je 99Cent.
